More than 45 percent of New York residents say "they don't feel so hot," according to a new survey. It's not because the temperature isn't as high as it normally would be this time of year, or because half of all New Yorkers are hypochondriacs and think they've come down with swine flu. It's because we're all stressed out—or that's what researchers think the culprit is, but since they didn't bother to test stress levels, they're not sure. Guess we'll all just have to wait and wonder (and not feel so hot). [Crain's]
